This Aluminum driveshell is a OEM factory replacement part
that comes standard on BMX bicycle hubs.

This driveshell does not come with bearings, but you have a couple of options
to complete your upgrade:

Purchase a bearing set which we will install here.
Then all you will need is two 5mm Allen wrenches to complete your
upgrade. Add $51.00 for the complete new set of bearings, which may
not be a bad idea anyway.

Move your existing bearings to this driveshell. If
you have a hub service tool, you can do it yourself. If you don't
have the service tool, you can have a local shop move the bearings
over for you, or send us your old driveshell and we will move your
bearings to your new driveshell and return it to you along with
your old driveshell. We move your bearings from one driveshell to
another at no charge.

NOTE: If you will be sending your old drive shell with
bearings to us, please let us know at the time of purchase so we know to expect
them.
